The power receptacle 110 includes a housing 305, one or more outlets 310 a, 310 b, and one or more shutters 315 a, 315 b. The housing 305 includes a rear cover 320 secured to a front cover 325. In some embodiments, such as illustrated, the front cover 325 includes openings for accommodating a RESET button 330 and a TEST button 335. Contained within the rear cover 320 and front cover 325 may be electrical and electronic components configured to receive and provide power to electrical devices 400 (FIG. 4 ) plugged into the one or more outlets 310. Further contained within the rear cover 320 and front cover 325 may be the components discussed above with respect to FIG. 2 . In some embodiments, the one or more shutters 315 a, 315 b are tamper resistant (TR) shutter mechanisms. On a singular basis, one of the outlets may be referred to herein as outlet 110 while the shutters may be referred to herein as shutter 315.

FIG. 4 is a perspective view of the power receptacle 110 receiving an electrical device 400. As illustrated, as electrical device 400 is plugged into the outlet 310 b, shutter 315 b is moved in a first direction 410 from a closed position to an open position. When either shutter 315 a, 315 b is moved in the first direction 410 to the open position, respective outlet 310 a, 310 b is determined to be in the unavailable state.

FIGS. 5 and 6 illustrate a cross-sectional view of the power receptacle 110 taken along line A-A (FIG. 3 ). FIG. 5 illustrates the power receptacle 110 in the available state (e.g., the shutter 315 b is in the closed position and the electrical device 400 is not plugged into the outlet 310 b). When the shutter 315 b is in the closed position, the shutter 315 is not in contact with switch 205 and switch 205 is not activated.

FIG. 6 illustrates the power receptacle 110 in the unavailable state (e.g., the shutter 315 b is in the open position and the electrical device 300 is plugged into outlet 310 b). When the shutter 315 b is moved in the first direction 410 to the open position, the shutter 315 b comes into contact with, and activates, switch 205. In some embodiments, the switch 205 is integrated into the shutter 315. Such an embodiment operates in a similar fashion to the embodiment of FIGS. 5 and 6 .

FIG. 7 illustrates a cross-section view of another embodiment of the power receptacle 110 taken along line A-A (FIG. 4 ). Such an embodiment further includes a switch arm 700. The switch arm 700 is configured to activate the switch 205 when the shutter 315 b is moved in the first direction 410 to the open position. Outlet 310 a and shutter 315 a operate in a similar fashion as outlet 310 b and shutter 315 b discussed above with respect to FIGS. 5-7 .

In some embodiments, the shutters 315 a, 315 b, receptacle controller 110, switches 205, and receptacle input/output module 210 are coupled to an interior of the front cover 325. In such an embodiment, the front cover 325 may be configured to releasably couple to an existing power receptacle. Such an embodiment, provides the same features as the power receptacle 110, discussed above, to a pre-installed power receptacle.

In operation, the power receptacle 110 is configured to output a signal respective of the current states (e.g., available or unavailable) of outlets 310 a, 310 b to the notification control unit 105. In some embodiments, the signal may include the type and number of available outlets or ports. The notification control unit 105 receives a plurality of signals from a plurality of power receptacles 110. The notification control unit 105 determines the current state of each power receptacle 110 according the received signals and outputs information concerning the current state of each power receptacle 110.

FIG. 8 illustrates an exemplary map 800 according to some embodiments of the present application. The map 800 may illustrate a public location, such as but not limited to, an airport, a bus station, a train station, and a restaurant. The map 800 illustrates the location and availability of one or more power receptacles 110, as well as their state, at a location. For example, in the illustrated embodiment, a filled circle 805 may indicate an unavailable power receptacle 110, while an unfilled circle 810 may indicate an available power receptacle 110.

In some embodiments, the map 800 further illustrates information concerning the power receptacles 110. For example, the map 800 may further provide a user with the type of power receptacle 110, as well as a number of available outlets, or port, of the one or more power receptacles 110. As discussed above, the map 800 may be sent to, or accessed by, the one or more user devices 115.

FIGS. 9A & 9B illustrate a notification system 900 according to some embodiments of the application. The notification system 900 includes a plurality of power receptacles 905 each housed within a power receptacle housing 910. In some embodiments, the notification system 900 and the plurality of power receptacles 905 may include similar components, and function in a similar, as notification system 100 and power receptacles 110, discussed above.

In some embodiments, each power receptacle 905 includes a circuit breaker for protecting the power receptacle 905 from, among other things, overcurrent. In such an embodiment, when one or more power receptacles 905 are placed in a tripped condition by the respective circuit breaker, the notification system 900 may output a notification. Such a notification may be output in a similar manner as discussed above with respect to the receptacle input/output module 210 of FIG. 2 .

As illustrated, in some embodiments, the power receptacles 905 are electrically connected together. In some embodiments, the power receptacles 905 may be electrically connected in a “daisy-chain” configuration, such that if one of the power receptacles 905 is placed in a tripped condition, all of the power receptacles 905 of the notification system 900 are placed in a tripped condition. In other embodiments, the power receptacle 905 may be electrically connected in a “parallel-type” configuration, such that if one of the power receptacles 905 is placed in a tripped condition, the other power receptacles 905 of the notification system 900 remain in a non-tripped condition.

FIGS. 10A & 10B illustrate a power receptacle 905 of the notification system 900. The power receptacle 905 includes one or more outlets 915 and one or more user-inputs 920. In some embodiments, the outlets 915 are substantially similar to outlets 310 a, 310 b, discussed above. The user-inputs 920 may be a power button, a RESET button, and/or a TEST button. Although not illustrated, in some embodiments, the power receptacles 905 further includes one or more shutters 315 (FIGS. 3-7 ).
